Slight digression, but...
Surely it's time for a better definition of the whole MATZ thing. The fact that participation by GA VFR traffic is *optional* is barmy, and anyway military ATCOs seem to regard it as a zone in which they can operate positive control (e.g. I was flying at an AEF on Wednesday and heard approach saying 'Aircraft entering MATZ at 1700ft at such-and-such position, what are your intentions?' followed by 'Aircraft in MATZ at such and such a position, leave the MATZ' - an instruction which surely he is not in a position to give? Didn't work anyway, he wasn't listening!) On the flip side, the aircraft in question was being very silly as the MATZ in question was very busy.
I don't want to encourage proliferation of Class D, but what's wrong with e.g. Class E CTRs or at least mandatory radio contact inside a MATZ?
